9.Google Nest Protect – Smoke Alarm And Carbon Monoxide Detector

In my testing, the Google Nest Protect performed admirably, activating its alarm after only two sprays of the aerosol. It had a loud alarm that could be heard from across the 2,700 square foot house in which I tested it, and its red LED flashed continuously while the alarm was sounding. When the sensor no longer detected any aerosol, the alarm and light both turned off at the same time.

To detect smoke, the Google Nest Protect lacks an ionization sensor and instead relies on a photoelectric sensor. This makes it slightly less sensitive to flash fires, but it also reduces the likelihood of nuisance alarms or false alarms caused by cooking smoke or steamy showers setting it off. Its screen shows the amount of carbon monoxide in the air in real time, the status of the unit during a test, and a battery level icon.

Installing the Google Nest Protect was simple, and I was able to attach it to the ceiling in about two minutes using a power drill and a pencil. The anchors are white, so they blend in with the ceiling, and they came in a resealable plastic baggie, which was useful.

How to buy the best smart smoke alarms

Smart smoke detectors are a specialized product. Few mainstream companies have released their own models, and startups appear to be having difficulty getting off the ground.

Smart smoke detectors vs. “hearers”
Detects carbon monoxide and smoke.
A smart detector combines smoke and carbon monoxide sensors into a single device, allowing you to monitor both threats while at home or away. Furthermore, it eliminates the need to check and maintain two separate monitors on a regular basis, providing you with additional peace of mind. Only smart detectors with both sensors were considered.

Certified for safety and performance
We made certain that every smoke and CO detector on our list had been vetted and approved by UL, a globally recognized third-party organization that tests the safety and efficacy of household products. A UL-certified alarm is guaranteed to detect and notify you of a fire or carbon monoxide leak in your home. And, thanks to updated UL standards published in 2018, newer models, such as the smart alarms listed here, are designed to recognize a broader range of flames and reduce false alarms.

carries out self-checks
The U.S. Fire Administration recommends that you test your smoke and CO detectors at least once a month. Failure to do so can be hazardous: According to a National Fire Protection Association study, one in every five home fire deaths occurred between 2009 and 2013 in a home where fire alarms were present but not working. This can occur when homeowners are unaware that a detector is no longer operational or has a dead battery.


For those who are already settled, it is a good idea to consider upgrading your units to newer models—or purchasing additional ones to create an interconnected system—to provide better coverage for your home. However, with so many options on the market and technical details that aren’t easily digestible at a glance, finding the right smoke detector for your family and setup can be difficult.
